Mercedes-Benz S-Class vs Cadillac Lyriq

What's the difference?

It's only in the running for the title of world's best luxury car. No biggie here, then.

Like Rolex and Concorde, S-Class has become a byword for ultimate, and deserved or not, the Mercedes-Benz defines its segment despite the best efforts of the BMW 7 Series, Audi A8, Lexus LS and (sadly now-defunct) Jaguar XJ, as well as pointing the way forward with new technologies that eventually trickle down to more proletarian models.

Replacing the half-million selling W222 unveiled in 2013, the W223 is the latest in a long line since the first W187 Ponton debuted in 1951, and includes the famous ‘Finnies' and Stroke-8 models that followed immediately afterwards, but it is the 1972 W116 that really set the template.

Now, seven generations in, the 2021 S-Class is all-new again, with progressive safety and interior features that should help keep it Australia's bestselling full-sized upper-luxury sedan.

General Motors Australia & New Zealand (GMANZ) has recently expanded its full-electric Cadillac SUV range in Australia from one to three models, with the new Optiq and Vistiq joining the pioneering Lyriq in the company's local line-up of luxurious US-sourced SUVs and pickups.

The five-seater Lyriq is now the happy medium of the Cadillac trio, as it’s positioned between the smaller Optiq and larger Vistiq; the latter with a unique seven-seat design.

We recently spent a week aboard the Lyriq to see if its opulence, practicality, performance, driving range and price provide a compelling alternative to full-electric or combustion-powered rivals for high-end luxury SUV buyers.
